Test build-and-push (self-test) / Build tiny multi-arch image (push) Has been cancelled
Builds a tiny inline alpine image through build-and-push against the remote buildx builder and asserts the pushed manifest is multi-arch. Pushes to a throwaway :citest tag so it never touches real images. Triggered on workflow_dispatch and on changes to the action.
